Meanwhile, we're still collecting internal fridge noises, and enjoyed this advert featuring the 'fridge eye view', thoughtfully sent in by @hlame. Special thanks are due to Julian Burgess and Leo Vegoda for the videos of the insides of their fridges - we hope to rip the audio and use it in future episodes!

Buy your own tape, make a video of yourself opening the envelope, and tell us about it on Twitter or by email. And you'll hear more about this on forthcoming episodes, but - tapes bought in the next few weeks have a reasonably high chance of being illustrated by our artistic SRS guests!
